We explore the impact of two-dimensional convective shell oxygen burning simulations on explosive nucleosynthesis in supernovae. Significant perturbations in density (5\%), temperature (1\%), pressure (3\%), and electron fraction (0.08\%) arise in one model of convective oxygen burning completed to date (Baz\'an and Arnett 1994). The electron fraction perturbation itself translates to a 36\% perturbation in neutron excess, $\eta$, which governs explosive nucleosynthesis. This attribute, plus the density and velocity perturbations induced by convection, are enough to describe the distribution of velocities of $^{56}$Ni blobs once a SN shock wave passes through the former oxygen burning shell. We explore the effects of initial shock wave models, dimensionality, and zoning on two-dimensional explosive nucleosynthesis in supernovae.
